NUT-HOLDER.

SPECIFICATION forming part of Letters Pat n N0. 770,144, dated September13, 1904.

Application filed January 5, 1904. Serial No. 187,845. (No model.)

To all whom, it may concern:

Be it known that we, GEORGE F. ZWILLING and CHARLES W. RIoHARDs,citizens of the United States, and both residents of Cleveland, in thecounty of Cuyahoga and State of Ohio, have invented a new and ImprovedNut- Holder, of which the following is a full, clear, and exactdescription.

This invention relates to a nut-holder designed especially for automaticnut-tapping machines.

The object of the invention is to provide means for holding the nut withthat firmness necessary to the operation of the tap therein and yetallowing the nut a certain bodily movement transversely of the tap, sothat should the nut not be true it may be shifted laterally as the tapenters the nut and the tap allowed to operate evenly notwithstandingthat the sides of the nut may not be true. In

attaining this end we provide a stand mounted on the table of themachine under the nutfeeding chute and having a nut-holder properarranged to slide horizontally therein laterally of the tap. Inthisnut-holder the nuts are held free to move vertically, and therefore itwill be seen that by these combined move ments the nut may be shiftedsidewise or upward, so that the orifice in the nut will correspondprecisely to the true position of the tap.

This specification is an exact description of one example of ourinvention, while the claims define the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a front elevation of the nutholder with parts in section.zontal section on the line 2 2 of l, and Fig. 3 is a verticallongitudinal section on the line 3 3 of Fig. 1.

indicates the bed or table of the nut-tapping machine, and the dottedlines 11 may be taken to represent the nut-feeding chute there- 0 stand12 of the nut-holder, said stand having a vertical passage 12 formedtherein, and a Fig. 2 is a hori Suitably mounted on the table 10 is thehorizontal passage 12, both of said passages crosslng each other andopening at the inner or rear side of the stand and the vertical passage12 running through to the front of the stand at the lower portion, asshown in Figs.

1 and 3, thus allowing the proper operation of the nut-ejector 14. Sofar as this invention is concerned this ejector 14 may be of any formdesired. e have illustrated in the drawings, however, an ejector similarto that disclosed in our application for nut-tapping machines, filedJune 12, 1903, Serial No. 161,181.

The nut-holder proper comprises a horizontally-extending block 15, whichfits snugly in the horizontal passage 12 of the stand, so as to movehorizontally therein. Secured. to the rear side of the block 15 are twopins 16,

against which respectively bear springs 17,

these springs serving to hold the block 15 yieldingly in its central orintermediate po- 'sition. ported on the stand. As here shown, they Saidsprings should be suitably supare attached to cleats or plates 18, whichare bolted to the rear sides of the stand and ex' .said liners 19, 21,and 22 extend above and below the block 15, as shown in Figs. 1 and 3,and they form a vertical chute, in which the nuts lie superimposed, asindicated by the broken lines in Fig. 3 and as is fully set forth in thecopending application above referred to.

The dotted lines 25 in Fig. 3 indicate the tap and show its positionwith respect to the nut-holder. The block 15 has a relatively largeopening 15 formed in its rear side, this opening communicating with thebefore-mentioned vertically-extending opening 15", and the liner 22 hasan openlng 22 therein corresponding with the opening 15 The front wallof the stand 12 has an opening 12 therein and the liner 19 an opening19, both in line with the opening 15 and the tap. The nut being tappedis dropped through the space between the liners 19, 21, and 22, and isheld by the coaction of the ejector let and thelowermost nut in positionto be engaged by the tap. As the tapered tap passes through the openings15 and 22 and engages the hole in the nut should the nut be out ofsquare or otherwise not true the block 15 will give to one side or theother, thus compensating by a lateral movement for the inaccuracy in thenut, and the nuts will be free to move upward in the chute, and in thismanner the compensating movements of the nut will be complete. In thisconnection it should be remembered that the springs 17 are set to holdthe block 15 normally in central or true position.

Various changes in the form, proportions, and minor details of ourinvention may be resorted to at will without departing from the spiritand scope thereof. Hence We consider ourselves entitled to all suchvariations as may lie within the intent of our claims.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent- 1. In a nut-holder, the combination of astand, and a nut-holder proper arranged to slide therein, the nut-holderproper having a nut-chute extending transversely of the line of slidingmovement.

. 2. In a nut-holder, the combination of a stand, a nut-holder properarranged to slide therein, the nut-holder proper having a nutchuteextending transversely of the line of sliding movement, and a spring foryieldingly holding the nut-holder in true position.

3. A nut-holder, comprising a stand having a horizontal and a verticalpassage, said passages crossing each other, a nut-holder proper arrangedto slide in the horizontal passage,

and walls carried by the nut-holder proper and lying loosely in thevertical passage of the stand, said walls constituting a chute for thenuts.

4. A nut-holder, comprising a stand having a horizontal and a verticalpassage, said passages crossing each other, a nut-holder proper arrangedto slide in the horizontal passage, walls carried by the nut-holderproper and lying loosely in the vertical passage of the stand, saidwalls constituting a chute for the nuts, and a spring for yieldinglyholding the nut-holder proper in true position.

5. A nut-holder, comprising a stand having vertical and horizontalpassages therein, a block arranged to slide in the horizontal passage,and liners carried by the block and extending vertically to form a chutefor the nuts.

6. A nut-holder, comprising a stand having vertical and horizontalpassages therein, a

block arranged to slide in the horizontal passage, liners carried by theblock and extending vertically to form a chute for the nuts, and aspring actuating the block to hold it yieldingly in normal position.

7. In a nut-holder, the combination of a stand, and a holder propermovable therein, said holder having a chute extending transversely tothe line of movement of the holder in the stand.

8. The combination of a nut-holder capable of receiving and bodilycarrying the nut, means for mounting the nut-holder so as to permitmovement thereof in one plane, and yielding means for holding thenut-holder in position.

In testimony whereof We have signed our names to this specification inthe presence of two-subscribing witnesses.
